Anxiolytic drugs side effects

Side effects. Because clobazam has been widely used as an anxiolytic, its side effects are well known and essentially similar to those of the other benzodiazepines. Thus sedation, dizziness, ataxia, blurred vision and diplopia are the most commonly reported in epileptic patients. One of the most problematic features of clobazam is its tendency to produce tolerance, an effect which may occur more frequently with clobazam than with the other widely used benzodiazepine, clonazepam. It has been estimated that at least 50% of patients develop tolerance. Tolerance to the sedative effects of the drug develop more rapidly than those to the antiepileptic effect. Clobazam should be considered as adjunctive therapy whenever treatment with a single first-line drug has proven to be ineffective. [Pg.311]

Anxiolytics are drugs used for the treatment of anxiety disorders. Apart from benzodiazpines, a frequently used anxiolytic is the 5HT1A (serotonin) receptor agonist buspiron, which has no sedative, amnestic or muscle-relaxant side effects, but whose action takes about a week to develop. Furthermore, it is less efficaceous than the benzodiazepines. Buspiron s mechanism of action is not fully understood. [Pg.201]

The development of the benzodiazepine class of drugs for the treatment of a variety of neurological indications has proven to be an outstanting success story in the field of chemotherapy. However, these compounds often produce undesirable side effects when used as anti-anxiety or hypnotic agents. These side effects include sedation, physical dependence, amnesia, muscle relaxation, and ethanol potentiation. The development of a benzodiazepine receptor-based anxiolytic agent devoid of these side effects would constitute a major advance in the field and has been the focus of significant research efforts [284]. [Pg.46]

Buspirone is an extremely specific drug that could possibly represent a new chemical class of anxiolytics—azaspirones. As an anxiolytic, its activity is equal to that of benzodiazepines however, it is devoid of anticonvulsant and muscle relaxant properties, which are characteristic of benzodiazepines. It does not cause dependence or addiction. The mechanism of its action is not conclusively known. It does not act on the GABA receptors, which occurs in benzodiazepine use however, it has a high affinity for seratonin (5-HT) receptors and a moderate affinity for dopamine (D2) receptors. Buspirone is effective as an anxiolytic. A few side effects of buspirone include dizziness, drowsiness, headaches, nervousness, fatigue, and weakness. This drug is intended for treatment of conditions of anxiety in which stress, muscle pain, rapid heart rate, dizziness, fear, etc. are observed in other words, conditions of anxiety not associated with somewhat common, usual, and everyday stress. Synonyms for buspirone are anizal, axoren, buspar, buspimen, buspinol, narol, travin, and others. [Pg.79]

No satisfactory randomised controlled trials have been published demonstrating the efficacy of carbamazepine in anxiety disorders, although it has a history of use as an anxiolytic in panic disorder and PTSD. It has an unfavourable side-effect profile (nausea, dizziness, ataxia) and multiple drug interactions due to induction of liver enzymes. [Pg.477]

Levorphanol (Levo-Dromoran) is an L-isomer morphi-nan derivative of morphine that is five to seven times more potent than morphine. It produces all of the side effects associated with morphine but less nausea. It is indicated for moderate to severe pain as a preoperative anxiolytic. It is often used in combination with thiopental to reduce the latter drug s anesthetic dose and to decrease postoperative recovery time. The o-isomer of levorphanol, dextrorphan, does not possess opioid analgesic activity but is a useful antitussive. [Pg.323]

Several Hi histamine antagonists (e.g., diphenhydramine, promethazine, and hydroxyzine) have been used as sedative-hypnotics, since they produce some degree of sedation. While this sedation is usually considered a side effect of their antihistaminic activity, in some cases the sedation is sufficient to allow the drugs to be used in the treatment of anxiety and sleep disturbances. For these drugs, the anxiolytic properties are thought to be a direct consequence of their ability to produce sedation. [Pg.361]

In summary, buspirone is an effective generalized anxiety treatment that differs from conventional antianxiety drugs in speed of symptom reduction and types of symptoms affected. Although buspirone might seem to be the drug of choice for treatment of chronic anxiety, it has not displaced the use of benzodiazepines in the treatment of anxiety, perhaps because of its side-effect profile [dizziness, sedation, nausea], slow onset of action, and the opinion of some clinicians that its anxiolytic efficacy is less robust than that of benzodiazepines. Buspirone is accepted as an anxiolytic treatment much more widely in the United States than in most other countries [Kunovac and Stahl 1995]. [Pg.361]

How is a specific objective within the R D portfolio, e.g. the search for anxiolytic drugs with a fast onset of action (like benzodiazepines) but lacking cognitive side effects and addictive potential (unlike benzodiazepines), to be partitioned and sequenced so that individual groups within R D, with their different approaches and methods, can be integrated sensibly into the project ... [Pg.146]

The benzodiazepines (BZDs), which were introduced nearly 40 years ago, were hailed as a breakthrough because they have fewer of the drawbacks of prior anxiolytics and sedative-hypnotics, are effective in a range of disorders, and are safe in combination with most drugs (except other sedatives), as well as alone in overdose, and are generally mild in terms of side effects. For these reasons, BZDs quickly became, and remain, among the most widely prescribed drugs worldwide. [Pg.229]

Antidepressant drugs, however, might have direct anxiolytic effects. That is, certain antidepressants such as paroxetine (Paxil) or venlafaxine (Effexor) can help reduce anxiety independent of their effects on depression.1,47 These antidepressants have therefore been advocated as an alternative treatment for anxiety, especially for people who cannot tolerate the side effects of traditional anxiolytics, or who might be especially susceptible to the addictive properties of drugs like the benzodiazepines.1,9,46 Moreover, antidepressants such as paroxetine or venlafaxine are now considered effective as the primary treatment for several forms of anxiety, including generalized anxiety disorder, social phobia, and panic disorder.4,29,53 Antidepressants, either used alone or in combination with antianxiety drugs, have become an important component in the treatment of anxiety. [Pg.72]
